Bellow is a great link explaining a plastic composition and a method to making solid parts directly into the rotomoulding process. This process may be handy for screw lugs etc…. Great Link.

So using the chassis model I have been able to determine the exact shape and size of the tank. The render below shows the tank. Using the volume calculator in solid works I was able to determine its exact capacity. The tank is 4ooL in size. I am still continuing the development of the baffle system.

As mentioned in the previous post, I am developing the CAD to level that will allow me to develop the final design of the tank. The CAD image bellow is a complete design of the chassis parts that will directly effect my design. This and several other drawing views will be used to accurately develop my tank.

CAD Landcrusier Chassis

Yesterday I took another visit to the Mansfield DSE depot to document the underside of the DSE’s Toyota Landcrusier. As my design reaches conclusion I have now found that I am a point where I must complete the CAD work of the final Landcrusier chassis in order to accurately complete my design. From the research I found that I know approximately how I want my tank to fit and be designed, but in order to calculate a final size I must completely construct the CAD so the tank can be measured accordingly. The size of the tank is important as requirements specify it must not be any less then 400L. The amount of area I can use under the tray will directly determine the amount of space taken above the tray. I will continue this process over the next few days to reach my aim of having a completely refined design by class next week.

Below are a few images that I have taken to document the underside of the DSE vehicle tray.

Tank Baffle’s and Roto Moulding Design Comp

I have been looking into a range of baffles that may be used in the design for my water tank. There is a large range of baffles out there, but what system I choose to you may be directly dependent on my manufacturing process. At this stage I have looked into tank separators and pours aluminium foam baffles. These two baffles will be the most practical for the tank as the foam could possibly be inserted afterward without having to create a join in the tank. However at this stage I am leaning toward separators. From what I can understand it may be possible to design a baffling system that can be roto moulded directly into the component. Over this week I will flesh out a few designs and after the break I will have a talk with Ian Wong to discuss my design approach. Rotational moulding also allows for a flame retardation additive.

These are images of numerous baffling systems out there.

Bellow is a link to the Royal Commissions Executive Summary. The summary basically summarizes the entire inquiry. I don’t intend to read the entire document as its massive however I will read the relevant chapters and the summary to see how the findings may potentially impact my design. This may be either directly or indirectly.
